Specification of Letters Patent;

ApplicationfiledMarch21,1914. serialimsaasia 1 y 1 Be it known that I, Fnnonroirl-l. lVAL- run, a citizen of the United States, residing 1 locking the spike in a tie; and to provide at Fennimore, in the county of Grant and State of Wisconsin, have invented certain new and useful Improvements in Spikes, of

which the following is a specification.

This inventlonrelates to ZLQIZIllIOtLd spike,

and the principal object of the invention is to provide an improved means for securely improved means for slightly raising the spike after being driven into place thus bringing the locking pawl into action.

Another object of the invention is to provide a spike of the kind described which can be easily and cheaply manufactured and l which is so constructedithat the spike will not be weakened. Another object of the invention is to sobe easily driven into the tie but will be prevented from working out of the tie after it has been locked in the tie.

This invention is illustrated in the accompanying drawings wherein- Figure l is a view showing the spike in place before it has beenlocked; Fig. 2 is a view similar to Fig; 1 showing the spike locked; Fig. 3 is a fragmentary view in elevation of the lower end portion ofthe spike; Fig. 4: is a perspective View of the plate which raises the spike and moves the locking pawl into anoperative position.

The spike 10 is provided with a rail-engaging head 11 which head has its lip provided with notches 12 so that the arms :13 extending from the plate 14 may be bent into the notches and preventthe plate from working from beneaththe lip. In orderto lock the spike, there is provided a pawl 15 which is pivotally mounted within the slot 16 upon the pin 17. The slot 16 is wider at its mouththan at. its inner end so that the pawl may freely move vertically in the opening and thus moved to an operative position.

It should also be noted that the pawl has its outer end cut at an incllne to form a cam edge which will hold the pawl in the position shown iirFig. 1 when driving the spike into the t1e. It should also be noted that the upperedge of the pawl has its outer end portion curved inwardly as shown at 18 thus formlngea sharp penetrating point at the end of the pawl.

When in use, the spike is driven into the place.

tie as shown in Fig. 1 withfthehead engag ing the base of the rail 19. Afterthe spike has been driven intothetie to the position shown in Fig. 1, the plate 14 will be driven beneath the lip of: the head .11 and will ra se the spike apshort'distanceso that the spike will be moved to the position shown in Fig. 2, and the pawl swung to the position shownin this figure. The arms 13 will then be raised and moved into the notches: or groove 12t11us preventing the. platefrom swung outwardly and therefore=thespike terfering with the spike being driven into extends out or theslot or openinglfi will dig into the tie when the spike is raised thus causingthe pawl to be swung down- The sh p. n of heravl .Whi

slipping out of place or worked from beneath the lip of the head 11. As the spike is driven into the tie, the pawl "will Be.

wardly to the locked position. The Wood of the tie will then fill in around the spike thus leaving the spike fitting. tightly in the tie and. securelyheld in place by the.

locking The spike will thus be seplawl. curely he d in the tie and will be prevented from being worked out of the tie by the pound ng or arring of a train passing over the :rails. An inspection of the drawings can moveintothe tie without the pawl in- T will readily show that the spike will not be weakened to a material extent since the openingor slot 16 is comparatively small and therefore will not cause the spike to easily break.

What is claimed is: 1. Aispike provided with a transversel extending opening. adjacent its penetrating end, the slotincreasing in size toward its ing beyond the outer end of the slot with its free end cut at an incline to form a cam edge and having the outer end of its upper edge curved inwardly to form a penetrating point, ahead at the upper end of outer end, a locking pawl plvotally mounted in said slot and having 1ts free end extendfree end extending beyond said spike and sharpened to form a penetrating point, a

head it'or provided with a railengaging lip, a plate fitting beneath said lip, and means releasably connecting said ---releasably holding plate with said lip. 1

3. A spike, a locking pawl pivotally con-f nected with saidspike with its free end ex,- tending beyond the "side of the spike and cut at an incline to form a camand'terminati-ng in a penetrating point, and means releasably" 4@..A.spike,\ a locking pawl carried by-said spike, and means connectedwith the head ofisaid spiketformoving said spike to apo- 'sition to move said pdsition.=:
